Resin vs. PC vs. Glass Lenses: Which One Fits Your Style?

When it comes to purchasing eyeglasses, one important consideration is the lens material. However, understanding the differences between lens materials can be a challenge for many people. A lack of knowledge about their characteristics and difficulty in recognizing lens quality can make this decision overwhelming. In this article, we will provide a brief overview of three common lens materials – resin, PC, and glass – to help you make an informed choice that ensures optimal visual experience and comfort.

Differences between resin, PC and glass lenses

Resin Lenses

Resin lenses are optical lenses made from resin through a precise chemical process.

Advantages

  • Lightweight: Resin lenses weigh only 1/2 to 1/3 of glass lenses at the same power and refractive index.
  • Improved Safety: These lenses havean even distribution of fracture stress and high stability, reducing the risk of sharp fragments in case of breakage.
  • High Light Transmission: Resin lenses offer a light transmission rate of 92%, surpassing that of normal glass lenses.

Disadvantages

Resin lenses are more prone to surface abrasion and chemical corrosion compared to glass lenses. Coating methods can address these issues but require extra care and maintenance.

 

PC Lenses

PC lenses, also known as space lenses, are made of polycarbonate (thermoplastic material) that is heated and shaped into a kind of lens.

Advantages

  • Impact Resistance: PC lenses are the most impact-resistant lenses available, being 12 times more resilient than regular resin lenses and 60 times more resilient than glass lenses. They are ideal for sports glasses and children's eyewear.
  • Lightweight: PC lenses are 57% lighter than glass lenses and 37% lighter than regular resin lenses, reducing pressure on the nose and ears.
  • Built-in UV Protection: PC lenses inherently provide UV protection, whether or not they are coated.

Disadvantage

PC lenses will be deformed by excessive heat and are not suitable for high humidity and heat occasions. In addition, PC lenses have higher requirements for the production process and need special grinding equipment to grind, so the price is more expensive.

 

Glass Lenses

Glass lenses are made from optical glass, a traditional material for eyeglasses.

Advantages

  • Heat Resistance: Glass lenses have good heat performance and quickly cool down without deformation.
  • Scratch Resistance: Glass lenses exhibit higher surface hardness compared to lenses made from other materials, making them more resistant to scratches.

Disadvantage

The material of glass lenses is heavy and very fragile, for the comfort of wearing a certain degree of influence, at present there have been very few people to use.
